TENSION DEVICE FOR FENCE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 436,006, datedSeptember 9, 1890.

Application filed March 29, 1890 Serial No, 345,901. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL LUTZ, a citizen of the United States,residing at Marietta, in the county of Fulton and Stateof Illinois, haveinvented certain new and useful Improvements in Tension Devices forFence-Machilies; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanyin g drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention aims to provide a simple and efcient tension device formachines for wiring wood fences.

In the drawings, Figure 1 is a top plan view, parts being broken away,of a machine embodying my invention. Fig. 2 is a side view, the tension-bars and guide -rollers being shown in cross-section. Fig. 3 is adetail front View of the tension-bars on the line x 0c of Fig. l.

The frame for supporting the operating parts is composed of thecorner-posts A, the top and bottom sills B and C, and suitablecross-bars D.

E and F are two cross-beams to receive the ends of the twisters journaled therein. There will be as many of these twisters as there arecables of wire in the fencing, two being shown to simplify matters.These twisters may be of any well-known construction, but it ispreferred to have them composed of a short-length tube G, which isclosed at each end by disks H, which have notches in their edgesdiametrically opposite to each other for the passage of the wires whichcomprise the cables. Midway of their ends these tubes G are providedwith sprocket or toothed rims I, by means of which the twisters aregeared together, being operated from the hand-wheel I', which isjournaled on a stud on the sideV of the standard J. This hand wheel hasspurs around it-s periphery, and a sprocketchain K passes around thiswheel and over the toothed or sprocket rims of the twisters,transmitting motion from said hand-wheel to the twisters. The cablesupport and picket holder is located immediately in front of thetwisting mechanism and comprises the rockshaft L, journaled at its endsin the top side beams of the frame. The plates M are secured to therock-shaft L and project therefrom at right angles. The treadle N isconnected by a strap n with the rock-shaft, the upper end of the strappassing nearly around the shaft, so as to effect a turning of the samewhen the treadle is pressed upon.

The reel on which the completed fencing is Wound is a shaft O, havingjournals at or near its ends, by which it is j onrnaled in the hingedboxes I on the top side beams or extensions C thereof. One end of theshaft O is adapted to receive the hand ratchet-wheel Q, by means ofwhich the said shaft is twisted to wind up the fencing thereon. The pawlq is provided to hold the shaft from turningback by engagement with thesaid ratchet-wheel.

The tension device is located lat the rear end of the frame, or thatopposite the reel, and -is composed of two bars R and R, which are heldtogether by a bolt, or more than one, if desired. In the rear of thetension-barsR and R are two rollers S andT to guide the wires betweenthe bars R and R. The spools of wire U are journaled on the corner-postsor other suitable portion of the frame. The guide rollers S and T arearranged upon dierent vertical and horizontal planes, and thetension-bars are on a higher plane than the roller S and between saidroller andthe twisters. Y

The operation of the machine is as follows: The wires Y from the spoolsU pass over the roller T, under the roller S, between the tension-bars Rand R', and through the twisting devices G, the ends being secured tothe reel. The picket is slipped endwise between the wires composing thecables, and is held in place by the plates M on the rock-shaf t,whichare caused to press against the said picket by bearing down on thetreadle N. The handwheel I is operated to turn the twister-s and twisttogetherthe wires between the picket and the twisters. After a picket issecured between the strands of the cable the reel is turned, by means ofthe hand ratchet-wheel Q, to wind the fencing thereon and draw the wiresforward to make way for another picket, which is secured between thewires, as hereinbefore described.
